Rotor Clip SH137ST Pa B100 External Retaining Ring

Product Description

The ROTOR CLIP SH137ST PA B100 is an external retaining ring designed to secure components on a 1-3/8 inch diameter shaft. Manufactured from SAE 1060-1090 carbon steel (UNS G10600-G10900) with a phosphate finish, this ring seats into a 1.291 inch groove diameter and delivers a hardness rating of 47-52 HRC for reliable retention under load. At 0.05 inches thick and 0.056 inches wide at the groove, it is sized for precision fits where axial component retention is critical. Maintenance technicians, millwrights, and mechanical assemblers install this type of fastener across a broad range of rotating equipment and shaft assemblies.

This external retaining ring is suited for shaft assemblies in industrial, mechanical, and trade-equipment applications where a secure, low-profile axial stop is required. Its phosphate finish provides a baseline level of corrosion resistance appropriate for controlled-environment installations. The ring is sold in a package quantity of 1 with a minimum order quantity of 100 units, making it a standard procurement item for maintenance shops, OEM assembly lines, and service operations that stock retaining hardware in bulk.

Compatibility

Designed as an OEM-style external retaining ring for 1-3/8 inch shafts with a groove diameter of 1.291 inches, suitable for mechanical assemblies that conform to SAE 1060-1090 and UNS G10600-G10900 fastener standards.

Installation Notes

Installation and removal of external retaining rings requires snap ring pliers sized for external-style rings. Always power down and de-energize equipment before servicing shaft assemblies. Inspect the shaft groove for wear or damage before seating the ring to ensure full and even engagement. Do not over-spread the ring during installation, as exceeding elastic limits will compromise retention force.
